Detailed Inspection and Maintenance (After 30 days of use - Every 6 months thereafter)
Bishamon recommends that every UniLift be inspected and maintained on a regular basis. Identifi ed below is a suggested detailed inspection and
maintenance checklist for normal operating conditions and environments. Extreme or unusual operating conditions may require a more extensive
inspection and maintenance program. If you have any questions regarding the inspection or maintenance of any UniLift, do not hesitate to contact
your local Bishamon dealer or Bishamon Industries Corp. The following inspection and maintenance items must be performed by a qualifi ed
service person.
WARNING
ALL
lift servicing must be performed by qualifi ed personnel only. Unauthorized modifi cations to the UniLift, its
hydraulic power unit or its control system may compromise the performance and safety of the system resulting in
SEVERE PERSONAL INJURY
and
PROPERTY DAMAGE.
UNDER NO CIRCUMSTANCES
should you attempt any repair or service that is not covered in this manual.
DO NOT
attempt to remove the constant force spring. The constant force spring is heavily preloaded and will recoil
violently if released.
ALWAYS
remove the load and
DEPRESS THE DOWN BUTTON
for several seconds to release the hydraulic
pressure before servicing the lift. The release of hydraulic fl uid under high pressure can be dangerous.
ALWAYS
disconnect the battery before servicing the electrical system. Not doing so could result in a
SEVERE
ELECTRICAL SHOCK.
The UniLift’s upper console cover, lower battery cover and mast cover must be removed to perform many of the detailed inspection and
maintenance items. To remove the upper and lower covers, follow the instructions in the previous section titled “Removing the Console and Battery
Covers”. To remove the mast cover, follow the instructions in the previous section titled “Disconnecting the Mast Cover”. After completing the
monthly inspection and maintenance, reinstall the covers. Use care not to damage the covers.
1.
Lubricate the parking brake guide tube and cam mechanism with Slick 50 One Lube or equivalent. Lubricate the locations identifi ed in
Figure 30. Check for smooth operation and proper wheel engagement.
2.
Inspect all the pivot points in the outrigger pivots and linkage pivots. To do so, raise the forks to the maximum pallet jack height and extend
both outriggers. After the left outrigger completely extends and both green Outrigger Extended LEDs are illuminated, release the UP
button. Both outriggers should be slightly off the fl oor. Turn the key switch to the OFF position. Thoroughly inspect the outrigger pivots
and linkage pivots identifi ed in Figure 31. Ensure all pins and retaining rings and in place and secure.
Check each outrigger linkage to ensure it is fully extended and over center. Grasp the roller end of the outrigger and attempt to move
the outrigger in and out. The outrigger should be tight against the stop bolt with little to no movement. As illustrated in Figure 32, the
